Bring clarity to 3-phase systems: When installing and connecting 3-phase motors and systems, it is important to check that the motor rotation direction and the rotating field direction of the wiring are correct. Incorrect connections can reverse the direction of rotation of the motor and thereby damage the motor and the equipment it operates. The PRM-5-EUR can be operated without a battery and is a simple and reliable checker for the correct rotating field direction of three-phase cables and sockets. The PRM-6-EUR has a clear, illuminated LCD display in addition to the functionality of the PRM-5-EUR and can use test leads to check the motor rotation direction of separate motors. An advanced feature of the PRM-6 is non-contact motor rotation detection, which detects the direction of rotation of the motor without test leads. This is particularly useful for fast-running motors where the motor rotation direction cannot be visually determined or when
the drive shaft is not visible. The PRM-5-EUR and PRM-6-EUR have a
sturdy construction with a rubber outer shell, are rated CAT IV 600 V and comply with EN 61010 and EN 61557. They are therefore ideal for testing the motor rotation direction and the rotating field direction in electrical systems up to 700 V in
commercial and industrial environments.
